His sister, Abigail Burling, was sentenced to 18 months after being found guilty of causing or allowing the death of a vulnerable person.

Jordan Burling, 18, was found by paramedics wearing a soiled nappy and weighing less than six stone on June 30 2016, the day of his death.

Opening his sentencing remarks, the judge told the women how it was “almost beyond belief” that Mr Burling “should have been allowed to die in his own house, here in Leeds, in 2016, in the bosom of his family”.

He said the pictures of Jordan in an emaciated state were “hauntingly reminiscent of starving victims of extermination camps in the Second World War”.

At the beginning of the sentencing hearing Mr Burling’s aunt, Susan Burling, read a victim personal statement on behalf of his father, Steven.

She said the family was trying to cope with a “living nightmare”.

The statement said: “I just can’t understand why all these horrific things have happened to me and my family.”
